Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A multicentre, single-blind, randomized comparison of a fixed clindamycin phosphate/tretinoin gel formulation (Velac) applied once daily and a clindamycin lotion formulation (Dalacin T) applied twice daily in the topical treatment of acne vulgaris.
A successful phase III pilot study compared the efficacy and safety of a fixed clindamycin 1%/tretinoin 0.025% gel formulation (CTG; Velac gel) applied once daily and a clindamycin 1% lotion formulation (CLN; Dalacin T lotion) applied twice daily in the treatment of moderate to severe acne vulgaris. ⋯ A single daily topical application of Velac gel was superior to Dalacin T lotion applied twice daily in reducing overall acne scores, and was faster acting. The simpler dosing regimen of Velac gel and its rapid effect are likely to have a positive effect on both patient compliance and cost.
